Abstract: Bringing together nanoparticles of intrinsically
different functionality constitutes a particularly powerful route to create
novel functional materials with synergistic properties found in neither of
the constituents. Nanoparticles (NPs) of different size and functionality (e.g.
noble metals, semiconductors, oxides, magnetic alloys) can self-assemble into
ordered binary superlattices isostructural to ionic and atomic compounds. In
the case of NPs, different types (e.g. Coulombic interactions, dipolar, van
der Waals, etc) equally contribute to the nanoparticle interactions that lead
to the diversity in binary superlattices. The difficulties encountered in co-crystallizing
more than two types of nanoparticle can be overcome by using multicomponent
nanoparticles. To date, multicomponent nanoparticles are represented by several
morphologies: (i) dumbbells; (ii) core-shell and recently discovered (iii)
hollow core-shell structures. Self-assembly of multicomponent nanoparticles
greatly extends the range and combinations of possible material types which
can be intermixed on the nanoscale. In addition to that, adjustments in the
nanoparticles composition is expected to allow control over particle-particle
interactions. The difference between nanoparticle-based solids with different
degrees of ordering will be discussed. The stability of the nanoparticle’s
surface will also be discussed.

Biography: Elena Shevchenko received her Ph.D. from
the University of Hamburg in Germany. She is currently a scientist at Argonne
National Laboratory in the Center for Nanoscale Materials, working on nanobio
interfaces. Before joining Argonne, she did research at the IBM Thomas J. Watson
Center, Columbia University and Lawrence Berkeley National Laboratory. She
was recently named one of the country's top young innovators by Technology
Reviews in recognition of her work in nanotechnology.

Pre-Dinner Talk by Dr. James P. Shoffner, UOP (Ret.):

“OECD: The Organization for Economic Cooperation
and Development; Its Origin, Evolution and Growth”

Born originally in 1948 after WW II as the “Organisation for European
Economic Co-operation” (OEEC), it was re-established as the larger, more
significant OECD in 1961. The organization grew slowly but significantly from
an original group of 20 member-nations to 30 in nearly 50 years. During January,
2010, OECD took in Chile as its 31st member-nation, the first South American
nation to ever belong. We will explore the origins, early history and present
work of this organization. Some comparisons will be made with other international
organizations that have world-wide reach such as the United Nations, World
Banks, etc. I will mention the prominence and influence that OECD has obtained
over the past ten years in terms of its media impact, overall societal reach,
and what we might expect from it in the future.
